The location and boundaries of the zoning districts
are hereby established as shown on a map entitled "Zoning Map of the
City of Haverhill, Massachusetts," dated December 6, 1971, and revised
July 22, 1991, which accompanies and is hereby declared to be a part
of this chapter.[1] The authenticity of the Zoning Map shall be identified
by the signature of the City Clerk and the imprinted Seal of the City
under the following words: "This is to certify that this is the Zoning
Map of the City of Haverhill, Massachusetts, referred to in the Zoning
Ordinance of the City of Haverhill, Massachusetts, which was adopted
by the City Council on December 7, 1971."

Editor's Note: A copy of the Zoning Map may be included in a pocket at the end of this volume. The official copy of the Zoning Map is on file in the offices of the Building Inspector and the City Clerk; see § 255-9B of this chapter.

Any change in the location of boundaries of a zoning district hereafter made through the amendments of this chapter shall be indicated by the alteration of such map, and the map thus altered is declared to be part of the chapter thus amended. The Zoning Map shall be drawn at a scale of one inch to 1,200 feet with ink on stable material. The Planning Board and the City Council shall, prior to their hearing on any amendment to this chapter where there is a change to the Map, cause notice of such hearing to be published and sent to parties of interest pursuant to § 255-101, Public hearing notices, of this chapter.

In order to maintain the up-to-date Zoning Map, the
following procedures shall be followed. The Zoning Map shall be the
original Mylar which shall be placed in the vault under the custody
of the City Clerk, and the official copy of which shall be located
in the office of the Building Inspector. Upon passage of a zoning
amendment affecting district boundaries, the City Engineer, at the
direction of the Building Inspector, shall make permanent changes
to the original reproducible Zoning Map Mylar and provide copies of
the corrected map to the Building Inspector, City Clerk, City Engineer,
City Council office and Planning Department. The date of all changes
and the authority for such changes shall be noted on the map, and
copies provided to each of the cited offices.

Where a boundary is indicated as a street, alley,
railroad, watercourse or other body of water, it shall be construed
to be the center line or middle thereof, or where such boundary approximates
a City boundary, then to the limits of the City boundary.

Where a boundary is indicated as following approximately
or parallel to a street, railroad, watercourse or other body of water,
it shall be construed to be parallel to the center line thereof and
at such distance from such center line as shown on the Zoning Map.
If no dimension is given, such distance shall be determined by the
use of the scale shown on the Zoning Map.

Where a boundary is indicated as intersecting the
center line of a street, railroad, watercourse or other water body,
and unless it is otherwise indicated, it shall be construed to intersect
at right angles to the tangent to the curve at the point of intersection.
